Whether you're a meditation practitioner seeking deeper states or a researcher prototyping wearable brain-computer interfaces, you'll assemble a device that provides immediate physiological feedback to train relaxation focus. Far beyond a simple blinky circuit, this build gives you hands-on experience with biopotential amplification, real-time digital signal processing on ESP32, and closed-loop feedback systems.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll construct a wearable headset that captures clean EEG signals from the prefrontal cortex, extracts alpha band (8-12 Hz) power in real-time using the ESP32, and drives a 12-LED WS2812B ring whose brightness and color shift with your alpha amplitude. A PAM8403 amplifier drives a speaker that generates a tone whose pitch varies inversely with alpha power—as you relax and alpha rises, the tone deepens, guiding you into a calm state.
